He had been concomitantly diagnosed with human immunodeficiency virus-1 (HIV-1) infection and disseminated tuberculosis in February 2006, after which he underwent a successful 12-month course of treatment for tuberculosis and antiretroviral therapy (ART: initially tenofovir/emtricitabine plus efavirenz followed by tenofovir/emtricitabine plus atazanavir/ritonavir), which led to a good recovery of CD4+ lymphocytes from 39/μL to 442/μL and controlled HIV-1 viremia (HIV RNA copy numbers went from 500,000 to <50/mL) until February 2011, when he was lost to follow-up. This evidence concerns the gene CD4 and tuberculosis.
